Since you're not on an app store that restricts your pricing flexibility, I think it's totally okay to raise your price later when you've gained stability. You won't really be irking anyone. I think making a more convincing sale value to early adopters is worth it, and later you can raise the price to justify the increased stability you will be offering to the risk-averse later-adopters. At worst you'll cause on-the-edge customers to suffer "loss by missing out" on the "deal" when it was cheaper, but that's not a bad thing. It's how airline ticket sales pages use cookies to tell if you're looking at the same flight 2 days in a row and raise the price by a couple tens of dollars to make you fear the price will keep going up if you wait too long to buy :)
